IN the United States, frequency-modulation has been assigned the wave band 42-50 m.c and at these frequencies, simplification in design and reduction in size of transmitters are of particular ...

Frequency modulation (FM) is the method of conveying informations over a carrier wave by varying its frequency .This is different from the Amplitude Modulation (AM) in which the amplitude of the ...

Many people think old AM transmitters are worthless. If a high-level, plate-modulated tube transmitter is replaced by a shiny new solid-state transmitter, why should the old one be kept? Heck, you ...

An experimental frequency modulated transmitter is described, giving a power output of 1 kW. It was originally designed to operate in the band 40-50 Mc/s, but by the addition of a doubling stage in ...

The mode of operation of the amplitude-modulated transmitter Class-C output stage is discussed, with particular references to the case where the load impedance varies over the working frequency band; ...

Puducherry: Puducherry station of All India Radio (AIR) today commissioned a state of art new 10 Kilo Volt transmitter installed at a cost of Rs 2.25 crores. The transmitter of Frequency Modulation ...

Many people think old AM transmitters are worthless. If a high-level, plate-modulated tube transmitter is replaced by a shiny new solid-state transmitter, why should the old one be kept? Heck, you ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...
